The Occupy Calgary protest campaign camp continues to grow near the Calgary Zoo and police say they'll allow it to continue as long as there's no threat to public safety.

There are now around 60 campers at the site on St. Patrick's Island.

The Occupy Calgary camp is designed to show support for the ongoing Occupy Wall Street demonstration in New York City.

Officially the site is a safe zone, with no drugs or alcohol however, some campers are complaining about drinking and marijuana use.

"A lot of people are using this place just as a place to drink and do drugs and have a safe place to sleep without the police harassing them and ticketing them," said Cassandra Keller.

Organizers admit there has been some conflict, but insist the camp is clean.

"There's no drinking and pot smoking on this camp. No one in this safe zone is allowed to drink and there's no alcohol and there's no drugs here," said Paul Hughes, Occupy Calgary Camp Manager.

Calgary police and bylaw officials say they are allowing the camp for now.

"Let's find out what they want. let's see what we can accommodate. They're not gonna get everything they're asking for, but I think the city has stepped up and said listen, we can accommodate part of this, we may not be able to accommodate all of it. Let's find that middle ground and I think that's what you're seeing happening here," said Kevin Brookwell of the Calgary Police Service.

Bylaw officials have brought in a fire pit, garbage cans and portable toilets for the campers comfort.

The protesters plan to march through the downtown core on Saturday.

The campers have permission to stay on St. Patrick's Island until the end of October.
